CGM Comparison

	A	B	C	D	E	F	G	H	I	J
1										What is this? My name is Marcus Grimm. I'm a Type 1 diabetic. In September of 2010, I decided to evaluate the Medtronic CGM, as compared to my Dexcom. These are my results, which you should only consider anecdotal as they would apply to you. Your diabetes will vary. Read more at http://pumprunner.com
2	Date	Time	Meter	Dex	Medtronic	Dex Delta	Med Delta	Dex +/-	Med +/-	Notes
3	9/24/2010	16:30:00	120	143	First Calibration
4		17:15:00	133	128	100	5	33	-5	-33
5		22:30:00	136	178	122	42	14	42	-14
6	9/25/2010	9:00:00	131	110	100	21	31	-21	-31	Both CGMs had similar waves throughout the night. Medtronic had no loss of signal. Dexcom had typical tiny losses here and there.
7		11:00:00	71	81	72	10	1	10	1	Mowed grass. Medtronic had "weak signal" error for a period for no good reason. No lost data, however.
8		15:30:00	81	110	114	29	33	29	33	Beginning to think that both systems have similar accuracy... Dex might have a bit less of a lag. Medtronic sensor is a bit more uncomfortable but not as unbearable as I feared, though it's only day 1.

11		23:00:00	209	192	176	17	33	-17	-33
12	9/26/2010	9:00:00	100	85	82	15	18	-15	-18
13		12:00:00	127	159	186	32	59	32	59	Just after 7.5 mile run. Another good example of Medtronic lagging behind Dex about 15 minutes. Both ended up in the same place, but Dex's lag is shorter.
